4SS*  A*  nitiduiu*  Atrum  nitidum,  breviter  fasco-pabescens,  protho- 
race  latitudiue  breviore,  lateribus  valde  rotundatis,  disco  aubtiliter 
minas  dense  puuctato,  ante  basin  trans versim,  disco  autem  vix  oon- 
Bpioue  impresso ;  elytris  subtiliter  dense  punctulatis,  obsolete  striatis. 
Long.  17.5  mm. 

One  male,  Oregon,  Lord  Walsingham.  This  species  is  larger, 
and  somewhat  more  robust  than  either  moestum  or  atrum,  and  is 
easily  known  by  the  surface  being  lustrous  instead  of  opaque, 
and  by  the  prothorax  being  much  less  densely  punctured.  The 
antennoe  of  the  male  are  half  as  long  as  the  body  and  stouter  than 
in  the  other  species,  especially  towards  the  base.  The  eyes  are 
of  the  same  form,  and  somewhat  hairy  as  in  the  other  species. 

Asmium  asperum  Lee.  belongs  properly  to  Nothorhina,  a  genus 
easily  distinguished  by  the  prosternum  being  more  deeply  oinar- 
ginate  in  front,  pronotum  longitudinally  excavated  in  the  middle, 
and  rough  with  elevated  points  at  the  sides. 

CRIOCEPHAI.V8  Muls. 
"  The  vaguely  described  North  American  species  introduced  by 
Kirby,  Randall,  and  Leconte,"  do  not  seem  to  have  merited  the 
recognition  of  Schiodte,*  and  I  have  therefore  constructed  the 
following  table,  which  may  assist  in  the  determination  of  speci- 
mens. 

r  Some  of  the  characters  used  by  Prof.  Schiodte  for  the  separa- 
tion of  the  tA^o  Danish  species,  become,  in  our  more  extensive 
fauna,  of  importance  in  defining  groups  rather  than  individual 
species,  which  may  accordingly  be  divided  as  follows  : — 

A.  3d  joint  of  hind  tarsi  emarginate  for  half  its  length,  the  4th  joint  con- 
sequently extending  as  far  as  the  lobes  of  the  3d  joint,  elytra 
finely  punctured : 
Antennae  and  legs  very  slender,  hind  tarsi  with  the  3d  joint  twice  as 
long  as  wide ;  body  more  elongate,  prothorax  not  wider  than  long, 
rounded  on  the  sides,  slightly  roughened  with  elevated  points. 

1.    PRODPCTPS  Lee, 

Antennae  and  legs  less  slender,  body  less  elongate,  prothorax  wider  than 
long :

3d  joint  of  hind  tarsi  two-thirds  longer  than  wide,  prothorax  rounded 

at  the  sides  and  slightly  roughened.  2.  aorestis  {Kirby). 

3d  joint  of  hind  tarsi  half  longer  than  wide,  prothorax  angulated  at 
the  sides,  and  strongly  roughened.  8.  aspebatus  Lee. 

.  3d  joint  of  hind  tarsi  bilobed,  cleft  nearly  to  the  base,  the  4th  joint 
received  into  the  emarginatiou,  not  extending  as  far  as  the  end  of 
the  lobes  ;  elytra  less  linely  punctured,  (sides  of  prothorax  rounded, 
scarcely  asperated): 
Prothorax  deeply  impressed,  hind  tarsi  with  3d  joint  nearly  twice  longer 

than  wide.  4.  uontands,  n.  sp. 

Prothorax  feebly  impressed,  hind  tarai  with  3d  joint  very  little  longer 
than  wide  ; 
Prothorax  very  finely  punctured.  5.  obboletus  {Rand.). 

Prothorax  less  finely  punctured.  6.  nhbilus  Lee. 

.  Eyes  smaller,  less  prominent,  and  more  deeply  emarginate  than  in  the 
other  species,  prothorax  and  elytra  finely  punctured,  the  former 
rounded,  not  asperated,  feebly  impressed  at  the  middle ;  3d  joint  of 
hind  tarai 7.  acstbalis  Lee. 


4S3.  C.  montanus. 

This  species  is  founded  on  four  specimens  from  Colorado, 
having  very  much  the  appearance  of  C.  product  us,  but  differ- 
ing by  the  3d  joint  of  hind  tarsi  cleft  nearly  to  the  base,  and 
by  the  less  finely  punctured  elytra.  The  prothorax  is  scarcely 
wider  tlian  long,  rounded  on  the  sides,  with  only  a  few  elevated 
points,  finely  and  densely  punctured,  with  the  two  discoidal  im- 
pressions, the  medial  channel,  and  two  tranverse  impressions 
deep.  The  hind  tarsi  are  slender,  the  2d  joint  is  more  than  twice 
as  long  as  its  width,  and  the  3d  is  about  half  longer  than  its 
width,  cleft  nearly  to  the  base.  The  antennae  of  the  Z  are  about 
three-quarters  as  long,  those  of  the  9 ,  one-half  as  long  as  the 
body.  The  ventral  sexual  characters  are  as  in  the  other  species, 
the  5th  segment  being  broad  in  the  %,  elongate  in  the  9  ;  in 
the  %  the  6th  segment  is  visible.     Length  19-24  ram.

australe  Lee,  Journ.  Ac.  Nat.  Sci.  Phila.,  2d  ser,,  ii.  35.  I  have 
seen  only  the  type  of  this  species,  which  on  account  of  the  finer 
punctuation,  and  general  appearance,  I  placed  in  Aseraura  from 
which  it  differs  by  the  eyes  being  larger,  more  coarsely  granulated, 
and  not  hairy.

OOIVOCALLVS  Leo. 

Body  elongate,  slender,  thinly  pubescent,  with  long  flying  hairs 
on  the  antennae,  legs,  prothorax,  body,  and  elytra ;  integuments 
of  firmer  consistence  than  usual  in  the  tribe;  front  short,  oblique, 
channelled,  divided  by  a  deep  transverse  line,  support  of  labrum 
coriaceous  as  usual.  Eyes  finely  granulated,  deeply  emarginate; 
gense  short,  prominent,  rectangular.  Palpi  short,  not  very 
unequal,  last  joint  broadly  triangular ;  antennae  slender,  thinly 
clothed  with  long  pubescence,  and  sparsely  villous  ;  scape  rather 
stout,  more  than  half  as  long  as  3d  joint,  2d  joint  about  one- 
fourth  as  long  as  3d  joint;  4th  joint  a  little  shorter  than  5th  joint ; 
11th  in  9  simple,  in  %  very  distinctly  divided,  outer  portion 
shorter.  Prothorax  shining,  sparsely  punctured,  sides  distinctly 
angulated  ^t  the  middle.  Elytra  elongate,  densely  punctured, 
rounded  at  tip.  Prosternum  narrow  between  the  front  coxae, 
which  are  transverse  and  broadly  angulated.  Mesosternum 
triangular,  obtusely  rounded  behind,  coxae  distant,  open  exter- 
nally ;  episterna  of  metathorax  not  very  wide,  nearly  parallel, 
tubercle  of  scent  pores  very  distinct;  5th  ventral  segment  shorter 
in  %  and  broadly  emarginate.  Legs  slender,  thighs  very  feebly 
clavate,  hind  tibiae  with  distinct  spurs,  tarsi  shorter  than  tibije, 
1st  joint  as  long  as  the  two  following  united. 

A  very  anomalous  genus,  founded  on  Gallidium  collare  Kirby 
(lepidum  Lee),  a  slender  black  species  with  bright  red  prothorax, 
found  in  Canada,  and  on  Lake  Superior,  By  the  greater  firm- 
ness of  the  tissues,  the  general  appearance,  the  presence  of 
an  additional  article  in  the  %  antennae,  and  the  smaller  size  of 
the  2d  joint,  it  forms  a  connecting  link  with  the  later  tribes 
allied  to  Olytini ;  but  by  the  broadly  angulated  front  coxae  it 
belongs  rather  to  the  Callidiini. 

The  eyes  are  more  inclined  to  embrace  the  base  of  the  antennae 
than  in  any  other  genus  of  the  Callidioid  series,  and  it  is  rather 
to  avoid  making  a  new  group  in  the  Cerambycoides  than  for  any 
other  reason  that  I  have  placed  it  here.

Mendocino,  California;  collected  by  Mr.  Behrens.  Readily 
known  by  the  small  size,  black  color,  and  coarse  sculpture,  riie 
thighs  are  strongly  clubbed,  the  front  coxae  are  contiguous,  and 
the  mesosternum  obtusely  triangular.  I  cannot  see  the  nioso- 
notum,  but  I  have  no  doubt  from  the  other  characters  that  there 
is  no  stridulating  surface.

Nevada,  Mr.  Ulke.  Two  specimens,  one  of  which  is  black, 
with  the  prothorax  ferruginous;  the  other  has  also  the  elytra 
brownish  ferruginous.  The  mesonotum  is  smooth  and  polished, 
with  a  few  scattered  punctures;  the  mesosternum  is  triangular ; 
the  thighs  strongly  clubbed,  the  front  coxae  contiguous.  G. 
sereum  Newman  (pallipes  ffald.),  belongs  to  the  same  division 
of  the  genus,  characterized  by  the  rather  stout  antennae,  not 
thickened  but  very  hairy  towards  the  base,  with  the  2d  joint  about 
half  as  long  as  the  3d,  and  the  punctuation  less  dense  than  in  the 
metallic  blue  species.

One  male,  Virginia  City,  Xevada,  Mr.  Edwards.  Nearly 
allied  to  X.  Agassizii  L'ec.,  but  the  prothorax  is  distinctly  nar- 
rowed behind  and  subsinuate,  very  much  as  Spondi/lis  iipifurtnis, 
and  the  sculpture  of  the  elytra  is  not  suddenly  finer  behind  the 
middle. 

The  convex  sides  of  the  prothorax  are  less  coarsely  and  more 
densely  punctured  than  the  disk.  The  antennae  are  two-thirds 
the  length  of  the  body,  quite  hairy,  and  the  4th  joint  is  very 
little  shorter  than  the  5  th. 


GA^IMUS  Lec. 

Head  moderately  large,  eyes  coarsely  granulated,  deeply  emar- 
ginate,  lower  lobe  very  large,  genae  extremely  short,  front  short, 
perpendicular;  mandibles  short,  stout,  acute  at  tip,  external 
outline  with  a  well-defined  obtuse  angle  near  the  tip,  so  that  the 
front  margin  is  straight  and  transverse  ;  palpi  very  unequal,  last 
joint  triangular,  obliquely  truncate.  Antennae  {%)  longer  than 
the  body,  11th  joint  indistinctly  divided;  1st  joint  thicker,  and 
about  two-thirds  as  long  as  the  3d  joint,  very  rough  with  small 
acute  spines,  3d  and  following  rough  but  gradually  becoming 
smoother,  fringed  beneath  but  not  densely  with  hairs,  which  also 
gradually  become  thinner  and  shorter.  Prothorax  wider  than 
long,  feebly  rounded  on  the  sides,  not  constricted  either  before  or 
behind,  transversely  impressed  before  the  base,  which  is  produced 
into  a  broad  subtruncate  lobe ;  disk  rather  flat,  with  a  narrow, 
smooth  dorsal  line,  and  two  vague  discoidal  impressions  ;  scutel- 
lum  broad,  rounded  behind ;  elytra  as  wide  at  the  base  as  the 
thorax,  gradually  narrower  behind,  and  rounded  at  tip.  Pros- 
ternura  laminiform  between  the  coxae,  but  not  prolonged  as  in 
Oeme ;  surface  in  front  of  coxae  finely  transversely  rugose,  and 
depressed  each  side ;  the  finely  roughened  dorsal  surface  extends 
on  the  flanks  to  the  prosternal  suture,  as  in  Eucrossus,  and  Oeme, 
in  which  the  prostemum  is  similarly  sculptured,  but  not  depressed; 
the  coxae  are  widely  angulated  externally,  and  the  whole  extent 
of  the  coxal  fissure  is  open,  though  not  so  widely  as  in  Oeme. 
The  mesosternum  is  very  narrow,  and  deeply  sunk  between  the 
coxae  which  are  very  large  and  prominent,  and  the  cavities  are 
widely  open  externally;  the  hind  coxae  are  prominent.  Legs  as

California,  Dr.  Horn.  This  genus  seems  quite  distinct  from 
any  described  in  Lacordaire's  work,  and  to  present  a  curious 
combination  of  characters.  The  well-defined  angle  near  the  tip 
of  the  mandibles  is  singular,  and  known  in  very  few  other  genera 
of  Cerambyciui.

California,  Mr.  Ulke.  The  male  has  the  antennae  as  long  as 
the  body ;  the  3 — 6  joints  are  armed  beneath  with  acut^  spines 
gradually  becoming  more  feeble. 

EIJCIIOSSUS  Leg. 

Body  elongate,  rather  depressed,  pale  brown,  without  markings; 
head  as  in  Oeme,  eyes  large,  coarsely  granulated,  deeply  emar- 
ginated ;  palpi  very  unequal,  labial  short,  maxillary  long,  last

Long.  18 — 24  mm. 

One  male,  Arizona.  Resembles  in  appearance  Oeme,  but  is 
les:3  slender ;  the  sculpture  of  the  prothorax  is  very  peculiar,  and 
the  dull  sericeous  surface  extends  upon  the  flanks  to  the  pro- 
sternum  ;  it  is  somewhat  similar  to  that  seen  in  Achryson, 
less  the  punctures  and  hairs  observed  in  that  genus ;  the  smooth 
dorsal  line  is  rather  broad,  and  abbreviated  near  the  base  ;  there 
is  on  each  side  a  large  cicatrix,  commencing  near  the  base,  ex- 
tending in  front  of  the  middle,  then  suddenly  bent  inwards 
for  a  short  distance,  and  then  turning  forwards  is  suddenly 
abbreviated.  They  resemble,  in  position,  the  scars  on  the  pro- 
thorax  of  the  %  of  some  of  our  large  species  of  Romaleum,  but 
are  much  broader. 

A  female  from  Owen's  valley,  California,  given  me  by  Dr.  Horn, 
differs  from  the  male  by  the  antennse  shorter,  thinner,  and  less 
hairy ;  the  5th  ventral  segment  not  truncate,  and  the  6th  not 
visible.  The  sides  of  the  prothorax  are  finely  punctured,  but  the 
disk  is  shining,  sparsely  and  coarsely  punctured,  and  somewhat 
uneven. 

There  is  great  variation  in  the  lateral  spine  of  the  prothorax  ;  in 
the  smaller  %  it  is  quite  absent,  and  the  sides  are  rounded ;  in 
a  large  %  from  California  it  is  small  and  acute,  in  the  t  it  ia 
still  more  prominent. 

HAPLIDUS  Lbc.  (Cerambycini). 

Body  elongate,  slender,  rather  depressed,  antennae,  prothorax, 
and  legs  thinly  clothed  with  long  flying  hairs,  of  which  a  few  are 
also  seen  on  the  front  part  of  the  elytra ;  front  short,  vertical ; 
eyes  large,  emarginate,  coarsely  granulated  ;  genae  short,  very 
acute ;  palpi  short,  equal,  last  joint  cylindrical,  truncate.  An-

the  sutural  spine  of  the  elytra  is  wanting,  the  tip  being  trun-

mediate between  the  Texan  specimens,  and  the  ordinary  i-gemi-

tral  spots  are  smaller  than  the  specimens  from  Georgia,  as  is 
usually  the  case  with  the  Missouri  specimens,  but  the  subapical 
protuberance  on  the  sides  of  the  prothorax  is  as  strong  as  in  any

one  is  short,  and  not  prominent ;  the  specimen  in  question  has 
them  equal  as  in  E.  i-geminala.  The  evidence  is  in  favor  of

more  so  than  in  the  four  preceding  species  in  the  synoptic  table,

In  one  specimen  the  inner  basal  ivory  spot  is  almost  wanting;

Sub-Qenus  ROMALEUM  VVhitb. 

The  species  of  this  sub-genus  differ  from  genuine  Elaphidion 
by  the  more  robust  form,  and  by  the  episterna  of  the  ractathorax 
being  distinctly  wider  in  front,  and  gradually  narrowed  behind, 
though  much  less  so  in  the  2d  division  than  in  the  1st.  The 
prothorax  is  comparatively  wider,  and  has  a  slight  tendency  to 
a  tubercle  on  the  sides  ;  the  pronotum  is  coarsely  punctured  with 
a  medial  and  two  dorsal  callosities  in  9,  very  densely  punctulate, 
with  a  posterior  medial  channel  and  dorsal  cicatrices  in  the  %. 
The  antennae  are  longer  than  the  body  in  %,  shorter  in  9,  the 
spines  are  never  long,  the  sensitive  spaces  are  distinct,  commenc- 
ing on  the  4th  joint  in  a  small  elongate  depression,  extending  on 
the  following  joints  so  as  to  occupy  gradually  the  whole  length  ; 
a  very  small  fovea  may  be  usually  seen  near  the  end  of  the  3d 
joint.  The  prosternum  is  always  rounded  behind,  and  the  raeao- 
sternura  gently  declivous.  The  femora  are  not  spinose.  The 
last  joint  of  the  palpi  is  less  dilated  than  in  genuine  Elaphidion.

Sub-Genus  ELAFHIDION. 

The  metathoracic  episterna  are  scarcely  wider  in  front  than 
behind,  and  there  are  no  distinct  sensitive  spaces  on  the  antennae ; 
the  antennae  are  longer  than  the  body  in  the  Z  and  shorter  in  the 
9 .  The  prothorax  of  the  %  in  some  species  is  more  finely 
punctured  than  in  the  9 ,  but  the  difference  is  never  as  obvious  as 
in  the  preceding  sub-genus  ;  the  prothorax  is  sometimes  rounded 
on  the  sides,  sometimes  straight,  and  usually  marked  with  dorsal 
callosities.  The  prosternum  is  sometimes  perpendicular  behind, 
in  which  case  the  mesosternum  is  suddenly  declivous  in  front, 
and  the  femora  spinose  at  tip;  otherwise  it  is  rounded,  the 
mesosternum  obliquely  declivous,  and  the  thighs  unarmed  ;  in 
the  second  case  the  elytra  are  sometimes  merely  truncate  or  even 
rounded  at  tip,  and  the  antennal  spines  occasionally  obsolete. 
The  scent  pores  are  usually  not  very  distinct,  sometimes  {E.  sub- 
pubescens)  remarkably  large,  sometimes  (E.  moestum)  appa- 
rently wanting.  The  legs  are  usually  finely  punctured  and 
pubescent,  without  distinct  flying  hairs,  sometimes  coarsely 
punctured  and  sparsely  hairy,  the  hairs  being  in  a  few  species 
very  long  (E.  pusillum).  The  body  is  more  or  less  densely 
pubescent,  except  in  E.  unicolor,  which  is  polished  as  in  Ibidion 
and  Sphaerion.

on  as  of  value  in  the  classification  of  Cerambycidoe,  that  there  is 
before  me  a  specimen  of  £J.  rufulum  in  which  the  left  front

the  fact  that  it  was  previously  described  (Trans.  Ent.  Soc.  Lond., 
3d,  i,  562)  as  Phacodes,  indicates  tolerably  clearly  that  the  genus 
Phacodes  should  be  partly  suppressed,  as  being  merely  a  slight 
Australian  geographical  variation  upon  Elaphidion.

ANEFLVS  Leo. 

This  genus  is  rendered  necessary  for  certain  species  which 
completely  resemble  the  elongate  forms  of  Elaphidion,  (subpu- 
bescens,  etc.),  in  appearance,  sculpture,  and  pubescence,  but 
difi'er  by  having  the  joints  of  the  antennse  from  the  5th  flattened, 
and  distinctly  carinate  along  the  middle  of  the  flat  sides.  The 
legs  are  coarsely  punctured  and  pubescent,  the  tibiae  are  finely 
carinate,  but  not  more  distinctly  than  in  many  species  of  Elaphi- 
dion, and  except  in  E.  tenue,  the  carinae  are  not  visible  on  the 
hind  pair;  the  spurs  are  well  developed.  The  1st  ventral  is 
evidently  longer  than  the  others,  and  the  5th  in  %  is  broadly 
Cinarginate, 

The  species  may  be  tabulated  as  follows : — 

A.  Prothorax  distinctly  dilated  and  feebly  angalated  on  the  sides ;  elytra 
bispinose  at  tip;  hind  tibisB  scarcely  carinate;  palpi  nnequal,  with

the  outer  angles,  the  4th  is  about  two-thirds  as  long  as  the  3d,  and 
armed  with  a  smaller  spine  ;  the  spines  of  the  5th  and  6th  joints 
are  very  small;  the  palpi  are  unequal,  and  the  last  joint  is  some- 
what, though  not  very  strongly,  triangular.  The  mandibles  are 
stout,  acute,  and  the  outer  margin  is  suddenly  bent  near  the  tip 
in  the  %  so  as  to  appear  transversely  truncate  (as  in  Axes- 
tinus),  but  is  regularly  curved,  and  normal  in  form  in  the  9. 
The  front  coxal  cavities  are  rounded,  not  at  all  angulated  exter- 
nally, and  only  narrowly  open  behind ;  the  presternum  is  rounded 
behind ;  the  mesosternum  nearly  perpendicular  iu  front,  horizon- 
tal, and  emarginate  behind  ;  coxal  cavities  closed  externally,  and 
scarcely  angulated.  Ventral  segments  slightly  decreasing  iii 
length,  5th  rounded  at  tip  in  both  sexes.  Legs  short,  stout, 
densely  and  coarsely  punctured,  tibite  strongly  cariuate,  and 
broadly  grooved,  spurs  moderate,  tarsi  broad,  1st  joint  of  hind 
pair  but  little  longer  than  the  2d. 

The  body  above  a*xd  beneath  is  punctured,  and  clothed  with 
rather  coarse,  yellowish-brown  hair ;  the  prothorax  has  several 
smooth  confluent  spaces,  the  intervals  being  very  coarsely  punc- 
tured ;  the  %  has  in  addition  a  large  lateral  densely  pubescent 
spot ;  the  scutellum  is  broad  and  rounded  behind,  the  elytra  are 
feebly  truncate  at  tip,  and  armed  with  a  small  sutural  spine.  The 
form  is  robust,  about  like  Elaphidion  atomarium. 

This  species  by  the  hairy  spaces  of  the  prothorax  shows  some 
resemblance  to  Stroviatium,  from  which  it -is  quite  distinct  by 
the  front  coxal  cavities  not  angulated  externally  as  well  as  by 
many  other  characters  above  detailed.

One  specimen  ;  Pennsylvania.  Of  the  same  form  and  size  as 
Tylonotus  bimaculatus,  but  quite  distinct  by  the  antennae  not 
being  sulcat^e,  the  prothorax  without  callosities,  and  the  piceous 
legs.     The  general  appearance  is  that  of  a  Callidium. 

It  is  quite  possible  that  this  genus  is  not  distinct  from  Zamiura 
Pascoe.  It  agrees  in  all  particulars  with  the  detailed  description 
given  by  Lacordaire,  1.  c.  viii.  215,  but  does  not  possess  the 
group  characters  of  Saphanides,  in  which  Zamium  is  placed  by 
my  learned  and  lamented  friend.  The  second  joint  of  the  anten- 
nse  is  quite  small  in  the  present  genus,  which  would  prevent  its 
association  with  Saphanus,  Opsimus,  etc.

PLECTROMERVI^  Lec. 

I  have  adopted  this  unpublished  name  of  Dejean  for  Callidium

by  Lacordaire,  1.  c.  viii.  352,  as  Curius ;  the  type  of  the  genus 
C.  dentatus  (concinnatus  Hald.)  not  having  been  'seen  by  him; 
he  has  mentioned  the  differences  in  a  note,  and  they  are  chiefly  as 
follows 

Body  depressed,  opaque  in  Curius,  cylindrical  and  polished 
in  Plectromerus ;  prothorax  rounded  on  the  sides  in  the  first, 
nearly  straight  in  the  second ;  4th  joint  of  antennae  a  little  shorter 
than  the  5th  in  the  first,  very  much  shorter  in  the  second.  The 
thighs  are  pedunculated,  and  suddenly  clavate  in  Plectromerus, 
and  the  tooth  is  much  larger  than  in  Curius,  in  which  they  are 
more  gradually  dilated.

PILEMA  Lec. 

This  genus  resembles  so  closely  the  European  Cartallum,  that 
no  detailed  description  is  necessary.  It  agrees  precisely  in  form, 
appearance,  and  general  characters,  but  difl'ers  by  the  palpi  being 
Blender,  with  the  last  joint  cylindrical  (not  triangular),  and  by 
the  mesosternum  being  wide  and  truncate  (not  narrow  and  sub- 
acute behind).     The  hind  tibiae  are  somewhat  curved.

not  deeply  transversely  impressed  at  the  base,  and  there  is  no

Two  %  have  the  prothorax  black,  the  base  of  th  tibiae  yellow, 
and  the  elytra  greenish-blue. 


Mi^GOBRIlJIW  Lrc. 

This  new  genus  is  founded  on  a  comppratively  large  species 
from  California,  which  is  intermediate  between  Cartallum  and 
Pilema,  having  the  palpi  with  the  last  joint  slightly  dilated  and 
oval,  truncate  at  tip,  and  the  mesosternum  narrow,  but  scarcely 
acute  as  in  Cartallum.  It  differs  from  both  by  the  prothorax 
being  longer,  with  the  lateral  tubercles  much  larger  and  obtuse, 
and  the  apical  and  basal  constrictions  longer,  equal  in  width. 
As  is  commonly  the  case,  in  intermediate  grades  of  structure,  the 
specific  characters  are  quite  different,  so  that  a  stronger  individu- 
ality is  thereby  impressed  on  the  organism.  The  color  is  testa- 
ceous ;  the  punctures  of  the  elytra  but  few,  not  coarse,  and  ar- 
langed  in  three  lines  extending  from  the  base  to  a  little  behind 
the  middle ;  there  are  a  few  scattered  punctures  between  these 
lines,  and  outside  of  them  ;  there  is  an  appearance  of  an  angu- 
lated pale  band,  with  the  point  directed  forwards  on  the  suture, 
in  front  of  the  middle,  and  a  few  nebulosities  behind.  The  anten- 
nae are  longer  than  in  rilcma,  and  the  outer  joints  are  compara-

CROS8IDIVS  Lbo. 

The  species  of  this  genus  vary  greatly  in  color,  and  are  some- 
what difficult  to  recognize  by  the  scattered  descriptions  here- 
tofore published.  I  have  constructed  the  following  table  to 
enable  them  to  be  more  easily  identified : — 

A.  Prothorax  anbquadrate ; 

Black  clothed  with  long  gray  hair ;  elytra  very  densely  punctured,  punc- 
tures very  coarse  at  the  baae,  becomiug  finer  behind  ;  front  tibi»  with 
a  dense  brush  of  hair  on  the  inner  side.     Utah ;  Eastern  California.

Oregon,  Lord  Walsingham  ;  California,  Dr.  Horn.  Easily  re- 
cognized by  the  coarser  punctures  of  the  elytra;  the  sutural 
blotch  varies  greatly ;  in  one  %  it  is  a  very  narrow  line,  in  two 
others  it  is  a  large,  oval,  elongate  spot;  in  two  9  it  is  broader, 
with  the  sides  straight  and  parallel. 

6.  G.  hirtipes  Lee,  Proc.  Acad.  Nat.  Sci.  Phila.,  vii,  16.  G. 
suturalis  Lee,  from  New  Mexico,  is  perhaps  a  local  variety  of 
this  species,  but  the  prothorax  is  less  densely  punctured,  the 
basal  margin  of  the  elytra  is  not  black,  and  the  body  beneath  is 
rufo-testaceous,  the  hind  tibiae  are  a  little  sinuate  on  the  inner 
side,  and  the  hind  tarsi  rather  broader,  with  the  1st  joint  less 
elongated  in  the  single  9  in  my  collection.

miniature  the  red  variety  of  G.  punctatus;  the  sutural  blotch  is 
broad,  with  parallel  sides,  and  extends  to  the  side  margin  by 
curving  outwards  about  one-fifth  the  length  from  the  tip.

Owen's  Valley,  California;  Dr.  Horn.  In  the  %  the  antennae 
are  a  little  more  than  half  the  length  of  the  body,  and  the  front 
tarsi  are  mach  broader  than  in  the  9 .  The  prothorax  is  quite 
distinctly  tubularly  constricted,  and  sinuate  on  the  sides  near  the 
base ;  the  hind  tarsi  are  less  slender  than  in  C.  marginicollis ; 
the  1st  joint  is  longer  than  the  2d  and  3d,  but  not  as  long  as  all 
the  others  united.  The  front  is  short  and  rounded  as  in  that  spe- 
cies. It  belongs  to  the  Ochrestes  group,  but  differs  from  any  of 
the  Mexican  species  which  are  thus  far  described. 

XYI.OTRECHVS  Chevb. 

The  markings  of  the  elytra  in  all  the  species  of  this  genus  may 
be  reduced  to  an  elementary  form,  consisting  of  a  scutellar  spot, 
an  arcuated  band  extending  along  the  suture  to  a  little  in  front 
of  the  middle  ;  an  oblique  band  behind  the  middle,  and  the  apical 
margin,  which  are  covered  with  pale  or  yellow  hair.  In  front  of 
the  arcuated  band  is  inclosed  a  marking  which  is  variable  in  form 
being  sometimes  (e.  g.  colonus)  a  slender  sinuated  transverse  line  ; 
sometimes,' as  in  most  of  the  species,  a  spot ;  sometimes  as  in  the 
three  following  species  a  line,  directed  inwards  and  backwards, 
but  reaching  neither  margin  nor  suture.  The  bicarinated  frontal 
elevation  also  differs  in  form  in  the  different  species,  and  affords 
good  characters  for  distinguishing  them.

DESORIPTIONS  OF  NKW  BPE0IE8. 


Colorado,  two  specimens  ;  the  markings  of  the  elytra  seem  to 
be  precisely  as  in  X.  insignis,  but  are  narrow,  and  the  black  ground 
is  sprinkled  with  short  cinereous  hair.  The  prothorax  is  more 
rounded  on  the  sides,  and  not  at  all  constricted  at  base. 

This  species  is  sometimes  placed  in  collections  as  X  vwrmonus 
Lee,  to  which  it  has  a  strong  resemblance  in  form,  and  by  the 
indistinct  markings,  but  differs  by  the  asperities  cf  the  prothorax 
being  very  much  finer,  and  by  the  frontal  umbo,  which  in  X.  mor- 
monus  is  broader,  more  acute  in  front,  flat  on  the  main  surface, 
and  margined  by  two  sharp  well-defined  distant  carinse.  The 
thighs  are  strongly  clubbed,  but  do  not  extend  to  the  tip  of  the 
abdomen.

One  specimen  from  Texas  kindly  sent  me  by  Mr.  A.  Sall<?. 
Tliis  species  has  the  same  form  as  N.  erythrocephalus,  but  differs 
by  the  coarser  sculpture  of  the  prothorax  (which  is  also  less 
rounded  on  the  sides),  and  by  the  bands  of  yellow  pubescence ;  on 
the  elytra  the  two  hinder  bands  are  more  oblique  backwards  from 
the  suture,  and  the  front  one  is  directed  as  much  forwards  in  this 
species,  as  it  is  backwards  in  N.  erythrocephalus.  The  front 
thighs  are  armed  beneath  on  the  posterior  margin  at  the  tip  with 
a  long  slightly  curved  spine,  represented  in  allied  species,  in  the 
form  of  an  obtuse  slightly  prominent  tooth  ;  the  hind  thighs  ex- 
tend to  the  tip  of  the  abdomen.

quent in  Texas  ;  the  dark-ground  color  of  the  elytra  is  sometimes 
thinly  suffused  with  white  pubescence,  especially  towards  the  base.

Texas ;  two  specimens.  I  saw  this  species  in  the  Oxford  museum, 
and  adopt  the  name  there  appended  to  it  with  great  pleasure,  as 
a  deserved  compliraeut  to  my  excellent  friend  Mr.  L.  lleiche  of 
Paris.  It  is  smaller  than  Eu.  picipes,  and  is  easily  distinguished 
from  similarly  colored  varieties  of  that  species  by  the  prothorax 
being  smooth  near  the  apical  margin,  and  not  longitudinally  pli- 
cate, but  only  punctured  on  the  rest  of  the  surface;  the  elytra  are 
similarly  sculptured,  but  the  sub-basal  tubercles  are  less  developed, 
and  the  ivory  band  is  exactly  transverse,  and  not  directly  slightly 
Wckwards,  as  in  that  species.     The  antenniB  are  not  spinose. 

Eu.  pini  Fitch  ;  Call,  pini  Oliv.,  CI.  piniadeas  Fabr.,  Gory,  and 
Lap.f  incorrectly  referred  by  Lacordaireto  Tilloniorpha,  is  closely 
allied  to  Eu.  picipes,  and  varies  in  color  in  the  same  manner ;  the 
prothorax  is  plicate,  smooth  at  the  apex  for  a  long  distance  as  in 
Reichei,  but  the  sides  are  rounded  in  a  different  manner  from  the 
other  two  species,  being  more  prominent  and  subangulated  at  the 
middle.  The  elytra  are  velvety  for  a  space  behind  the  ivory  band, 
which  is  slightly  oblique  as  in  picipes,  but  the  sub-basal  eleva- 
tion is  more  developed,  and  there  is  an  oblique  band  of  silvery 
hair  at  one-third  from  the  apex,  which  is  frequently  accompanied 
towards  the  suture  by  a  shorter  line  placed  in  front  of  it. 

The  eyes  are  completely  divided  as  in  the  other  species,  but 
the  upper  lobe  is  much  smaller,  and  reduced  in  fact  to  a  very  few 
lenses,  thus  approaching  the  genus  Tillomorpha,  in  which  the 
upper  lobe  is  entirely  wanting.

*  It  is  proper  to  note  here  tlie  oocurrenoe  in  Tex.ia  of  Gnaphalodes  tra-

to  Group  II  of  Cerambycini,  and  would  be  properly  placed  in  the  table 
(Clasaif.  302)  before  Chion,  with  the  following  detinition  : — 

Prothorax  with  lateral  spine  behind  the  middle  ;  antennae  densely  fringed 
beneath,  inner  angle  of  joints  4-7  apinoae ;  elytra  bispinoae  at  tip  : 
epiaterna  of  metathorax  wide,  soent  pores  distinct.        Gnapualodbs. 

The  Bcutellum  la  triangular,  larger  than  in  Chion,  and  the  eyes  are  leas 
coarsely  granulated :  the  proaternum  is  perpendicular  behind,  and  the 
mesosternnm  convex.  The  body  is  brown,  unifor-nly  clothed  with  gray- 
brown  pubescence,  paler  and  more  dense  on  the  acutellum.

Oce  pair,  Cape  San  Lucas,  Mr.  Xantns.  This  fine  species  differs  from 
the  others  by  the  antennae  being  armed  with  small  spines  ;  they  are  very 
distinctly  carinate,  in  the  %  are  nearly  as  long  as  the  body,  and  in  the  $ 
scarcely  two-thirds  as  long.  The  under  surface  and  legs  are  finely  pube- 
scent, and  speckled  with  darker  punctures  from  which  proceed  the  flying 
hairs.  The  5th  ventral  of  the  %  is  slightly  truncate,  emarginate.  The  last 
joint  of  the  palpi  is  elongate  triangalar,  less  dilated  than  in  A.  volitana, 
and  transversely  truncate  ;  the  appearance  of  a  transverse  line  across  the 
disk  of  the  prothorax  In  front  of  the  middle  is  the  result  rathor  of  the 
arrangement  of  the  pubeacence  than  of  a  positive  elevation  ;  the  tubercle 
each  side  is  transverse,  near  the  base,  and  nearer  the  side  than  the  median 
line;  there  are  a  few  large  scattered  darker  punoturea  upon  the  aidea. 

This  fine  species  was  overlooked  in  my  boxes  until  too  late  to  print  the 
description  on  p.  186,  where  it  properly  belongs.

DESCRIPTIONS   OF    NEW   SPECIES. 


One  flpociriCn  from  Florida,  given  rae  by  Dr.  E.  Brendel  ; 
another  in  the  collection  of  Mr.  UIke  is  entirely  black.  I  have 
mentioned,,  on  p.  321  of  the  Classification,  some  of  the  structural 
differences  between  this  and  Agaliifisia  gratus  (Hald.),  which 
entitle  them  to  rank  as  distinct  genera  ;  and  which  may  be  briefl'^ 
Slimmed  up  as  follows  :  in  AgJ.lissus  Dalman,  front  quadrate 
oblique,  prothorax  rounded  on  the  sides;  elytra  gradually  nar- 
rowed behind,  broadly  truncate,  and  serrate  at  tip,  with  the  sutural 
spine  quite  prominent;  body  finely  punctured  above,  smooth  be- 
neath :  in  Zagyujnus,  front  short,  vertical,  prothora.it  longer  than 
wide,  feebly  rounded  on  the  sides ;  elytra  para^llel,  not  narrowed 
behind,  rounded  at  tip,  with  the  sutural  spine  small,  body  very 
coarsely  punctured  above,  moderately  punctured  beneath. 

The  narrow  cpipleurns  are  in  this  tribe  suddenly  and  strongly 
sinuate  near  the  base,  a  singular  character,  which  att-acted  my 
attention  before  I  was  acquainted  with  the  description  of  Dalmnn, 
and  induced  me  to  place  the  only  species  known  to  me  as  a  dis- 
tinct primary  group  of  the  subfamily  Cerambyeida).

San  Francisco,  collected  by  Mr.  J.  Behrons.  Of  the  same  form 
as  N.  Imncollis,  but  easily  known  by  the  antennae  being  stouter, 
with  the  4th  joint  comparatively  shorter  ;  by  the  long  and  dense 
pubescence;  by  the  prothorax  (when  the  pubescence  is  abraded) 
being  sparsely  punctured,  and  by  the  elytra  being  impressed  nearer 
the  apex,  and  more  suddenly  concave.  The  color  varies ;  one 
specimen  is  black,  with  exception  of  the  disk  of  the  elytra,  and 
the  pednncle  of  the  thighs :  in  another  the  antenna;,  legs,  and 
elytra  are  ferruginous,  with  a  dusky  cloud  on  the  latter. 

I.EPTAI.IA  Leo. 

This  genus  is  established  on  Anoplodera  macilenta  Mann.  It 
is  allied  to  Encyclops,  having  uoarly  the  same  form  of  head,  con-

stricted  suddenly  but  slightly,  far  behind  the  eyes,  which  are  finely 
granulated,  and  feebly  emarginate  on  the  inner  side ;  the  hind 
angles  of  the  head  are  obtuse  and.  rounded  ;  the  antennae  are  long 
and  slender,  as  in  Encyclops,  and  the  4th  joint  is  a  little  shorter 
than  the  3d  and  5th,  they  are  inserted  well  up  on  the  front,  which 
is  less  vertical  than  in  Encyclops,  and  the  mouth  is  a  little  longer. 
The  last  joint  of  the  palpi  is  triangular  and  obliquely  truncate. 
The  prothorax  is  narrower  than  the  head,  longer  than  wide,  deeply 
constricted  before  and  behind,  and  the  sides  are  obtusely  but 
strongly  dilated.  The  elytra  are  wider  than  the  thoiax,  elongate, 
parallel,  feebly  truncate  at  tip.  Legs  slender,  tarsi  long,  Ist  joint 
of  all  much  Icujger  than  the  2d,  of  the  hind  tarsi  the  1st  and  2d 
joints  are  feebly  sulcate,  with  a  narrow  line  of  pubescence  each 
side ;  3d  joint  of  all  the  tarsi  dilated  and  deeply  bilobed,  as  in 
Encyclops. 

The  species  is  black,  densely  punctured,  the  head  and  protho- 
•  rax  more  finely  than  the  elytra.  Varieties  occur  with  yellow 
elytra,  with  the  suture  and  broad  sublateral  vitta  black  ;  A. 
Frankenhajuseri  Mann.,  is  a  variety  in  which  the  elytra  have 
only  the  black  vitta,  and  the  legs  are  testaceous ;  Leptura  fusci- 
collis  Lee.  is  a  larger  variety  from  California,  of  still  paler  color, 
the  body  being  testaceous,  and  the  elytral  vitta  very  indistinct.

narrower  at  tip  than  at  base,  and  there  is  no  appearance  of  lines 
on  the  elytra.  The  antennae  are  shorter  and  stouter,  but  this  is 
in  part  or  in  whole  a  sexual  character,  the  9  of  C.  aublineata

DESCKIPTIONS   OP   NEW    SPECIES. 


One  female,  Oregon;  collected  by  Lord  Walsingham,  and 
kindly  given  me  by  Mr.  G.  R.  Crotch.  The  antennae  are  about 
three-fourths  the  length  of  the  body.  This  species  resembles 
entirely  the  figure  of  the  European  X.  Spinolae*  except  that 
the  basal  and  subapical  spots  of  the  elytra  are  wanting,  and  only 
the  two  marginal  ones  remain  ;  these  are  transverse,  and  directed 
towards  each  other  in  a  diagonal  direction,  and  extend  nearly 
one-half  the  breadth  of  the  elytra.  The  genuL  is  very  closely 
allied  to  Centrodera  Lee,  and  dilFers  only  by  the  eyes  bein"* 
smaller,  less  transverse  and  less  prominent,  and  by  the  sides  of 
the  head  being  prolonged  behind  the  eyes,  suddenly  but  feebly 
constricted  at  the  base  (somewhat  as  in  Encyclo^,  etc.,  though 
to  a  less  degree),  instead  of  being  obliquely  narrowed  to  the  neck. 
These  diflferences  are  not  generic  in  Acmaeops,  nor  is  the  form  of 
the  head  and  eyes  constant  in  Leptura.  I  am  therefore  disposed 
to  believe  that  the  two  genera  are  not  suflSciently  distinct.  Those 
who  agree  to  combine  them  will  adopt  the  generic  name  Xylos-- 
teas  as  having  many  years  priority  over  Centrodera  Lee.

One  denuded  specimen  from  Yellowstone  basin.  Dr.  Horn, 
and  another  well  preserved  in  Mr.  Ulke's  collection.  Differs  from 
all  the  other  species  before  me  by  the  less  deeply  constricted  pro- 
thorax  and  more  obtusely  rounded  lateral  tubercles  ;  the  eyes  are 
smaller  than  usual,  and  finely  granulated,  but  more  convex  than 
in  T.  vestitus,  with  which  it  agrees  in  this  character;  the  3d  and 
5th  joints  of  the  antennae  are  equal,  and  the  4th  is  two-thirds  as 
long ;  the  head  is  feebly  narrowed  behind,  but  not  rounded  on 
the  sides.  The  pubescence  is  extremely  short  and  f^  < .  The 
species  of  this  genus  are  not  alike  in  the  e}es;  in  T.  <  <  t'.iop- 
terus  they  are  much  larger,  and  less  finely  granulated,  thuu  a  r»y 
of  the  others.

Oregon ;  Mr.  Ulke.  Related  to  P.  liturata  Kirby  (riitens 
Lee),  but  much  broader,  with  entirely  diffei-ent  sculpture,  and 
with  much  longer  thoracic  spines  ;  the  humeral  regions  of  the 
elytra  are  very  prominent,  and  the  disk  is  broadly  concave  inside 
of  them ;  a  broad  oblique  groove  runs  from  below  the  humeral 
prominence  on  to  the  dorsum  of  the  elytra  where  it  is  lost ;  the 
black  space  extends  along  the  outer  margin  obliquely  from  just 
behind  the  middle  to  the  sutural  tip.  The  antennae  and  other 
organs  are  as  in  P.  liturata.

One  pair,  Canada.  The  male  has  the  antennas  two-thirds  as 
long  as  the  body,  and  the  elytra  slightly  narrowed  from  the  base ; 
in  the  female  the  antennae  are  shorter,  and  the  elytra  broader, 
and  parallel  on  the  sides.  The  head  and  thorax  are  densely  and 
coarsely  punctured,  the  latter  narrower  in  front,  with  the  usual 
transverse  constrictions  before  and  behind  ;  the  lateral  tubercle 
is  acute;  the  disk  is  feebly  foveate  each  side,  and  the  dorsal  line 
is  narrow  and  somewhat  channelled.  The  sculpture  of  the  elytra 
is  very  peculiar,  consisting  of  a  reticulation  of  smooth,  strongly 
elevated  lines  with  the  depressed  spaces  coarsely  punctured,  from 
the  punctures  proceed  rather  coarse  golden  hairs;  at  the  mid- 
dle there  is  a  narrow  transverse  waxy  band. 

I  have  seen  specimens  of  this  insect  in  the  British  Museum 
under  the  names  P.  rugipennis  J^-Newman,  and  P.  bimaculata 
J^DeJ.     I  have  adopted  the  former  as  being  more  applicable.

One  female ;  southeastern  California,  Dr.  Horn.  Not  unlike 
in  form  the  stouter  species  of  Acmaeops,  but  the  eyes  are  larger, 
subtriangular,  and  strongly  and  broadly  emai'ginate  at  the  antero- 
interior  side.  The  antennae  are  a  little  more  than  half  the  length 
of  the  body,  and  stout ;  the  4th  joint  is  two- thirds  as  long  as  the 
5th,  and  a  little  shorter  than  the  3d.  The  punctures  of  the  head 
and  prothorax  are  rather  fine,  and  the  latter  is  not  channelled. 
The  elytra  are  somewhat  shining,  sparsely  and  not  finely  punc- 
tured at  the  base,  and  along  the  sides  beyond  the  middle,  the 
punctures  becoming  gradually  finer  towards  the  suture  and  behind, 
where  the  surface  is  nearly  opaque. 

A.  mirijicuii  Bland,  is  a  much  larger  species,  with  much  more 
coarsely  punctured  head  and  prothorax,  the  latter  broadly  chan- 
nelled, and  the  elytra  punctured  and  rugose  before  the  middle, 
opaque  and  scarcely  punctured  behind.     It  is  found  in  Colorado. 

ACMiEOPS  Leg. 

I  regret  to  say  that  owing  to  the  want  of  sufficiently  extensive 
sets  of  specimens  I  have  unnecessarily  multiplied  the  species  of 
this  genus,  on  slight  difierences  in  color,  pubescence,  or  sculpture, 
which  larger  collesctions  have  shown  to  be  merely  individual,  and 
not  of  specific  value.  With  the  increased  material  now  accessi- 
ble I  would  arrange  the  species  as  follows  : — 

A.  Short  stout  species,  with  the  head  narrowed  behind  but  not  oonstrioted, 
antennee  ratlier  stout  (except  in  tlioraoioa),  with  the  4th  joint

straight  and  parallel  behind  the  middle,  as  in  A.  atra,  and  quite 
distinct  from  them  as  from  all  others  by  the  punctures  of  the 
basal  half  of  the  elytra  being  arranged  so  as  to  give  the  appear- 
ance of  faint  longitudinal  stripes,  of  which  the  inner  one  runs 
obliquely  forwards  towards  the  humerus,  so  as  to  tend  to  unite  with

and  by  the  bead  being  obliquely  narrowed  behind  the  eyes,  and 
from  both  by  the  prothorax  being  less  densely  punctured,  more

California';  .Dr.  Horn.  A  slender  species,  proportioned  some- 
what like  A.  longicornis,  but  with  the  elytra  more  flattened,  and 
more  densely  punctured.  The  head  is  gradually  narrowed  behind 
tiie  eyes,  as  usual,  but  is  very  distinctly  constricted  though  not 
strongly  at  base,  showing  thus  an  affinity  with  the  Encyclopa 
tribe ;  I  should  be  disposed  to  place  it  in  that  tribe,  next  to 
Leptalia,  but  the  mouth  is  too  long,  and  the  front  not  sufficiently 
vertical  to  warrant  it.

line  more  elevated,  the  posterior  impression  less  curved,  the  middle 
lobe  of  the  base  with  a  distinct  transverse  elevation  near  the 
margin,  and  finally  by  the  elytra  being  each  marked  with  four 
vague  wide  grooves,  reaching  neither  the  base  nor  the  tip,  and 
presenting  somewhat  the  appearance  observed  in  Tragidion.

I  have  never  seen  a  specimen  of  aoror  with  the  autemedial  spot, 
which  is  but  rarely  absent  in  the  former.  The  prothorax  is  some- 
times entirely  black,  someticies  with  the  disk  and  prosternum 
black,  and  all  the  margins  yellow ;  the  head  is  usually  black, 
with  the  mouth,  and  antennal  tubercles  yellow ;  the  trunk  is  some- 
times entirely  black,  sometimes  black  only  at  the  sides  ;  the  legs 
are  testaceous,  with  the  tarsi  darker,  and  in  one  specimen  the 
hind  thighs  are  dusky  at  tip.  The  sexual  characters  are  as  in 
L.  obliterata.

this  as  one  of  the  varieties  of  the  Protean  L.  instabilis^  but  the 
elytra  are  less  dehiscent  and  more  broadly  rounded  at  tip,  the

One  9  ;  California,  Dr  Horn.  Quite  different  from  the  neigh- 
boring species  by  the  coarser  punctuation  ;  the  sides  of  the  tho- 
rax are  subsinuate  and  less  distinctly  angulated  than  in  L.  insta- 
bilis, and  the  mouth  and  genoe  are  shorter.  In  this  latter  character 
it  resembles  L  Matthewsii;  the  form  4s,  however,  stouter,  the 
antennae  thicker,  and  the  punctuation  much  coarser. 

Since  publishing  the  description  of  L.  Matthewsii  I  have  re- 
ceived from  the  same  collection  a  male.  It  differs  by  less  robust 
form,  and  very  long  antennae,  one-fourth  longer  in  fact  than  the 
body,  and  stouter  than  in  the  9 .  There  is  scarcely  any  ventral 
difference  between  the  two  sexes.     The  apical  blotch  of  the  ely-

One  9  ;  Mendocino,  California,  sent  by  Mr.  Jas.  Behrens  to 
Dr.  Horn.  This  species  is  apparently  the  western  analogue  of 
L.  S-notala,  but  is  much  larger,  and  the  spots  are  differently 
formed  and  arranged.  It  gives  me  much  pleasure  to  dedicate 
this  species  to  the  industrious  and  intelligent  gentleman  by  whom 
it  was  collected,  who  by  his  labors  has  greatly  added  to  our 
knowledge  of  the  entomological  fauna  of  the  Pacific  States. 

The  antennae  are  slender,  more  than  half  the  length  of  the  body, 
the  4th  joint  about  two-thirds  the  length  of  the  5th  joint.  The 
spots  on  the  elytra  are  pale  yellow  ;  one  near  the  base,  extending 
obliquely  inwards,  an  oblique  fascia  running  from  the  margin  a 
little  in  front  of  the  middle,  a  second  broader  fascia  behind  the 
middle,  connected  with  the  first  near  the  suture,  so  as  to  inclose 
a  large  subquadrate  lateral  spot ;  another  large  spot  near  the  tip, 
attaining  neither  the  suture  nor  margin. 

Should  the  yellow  spots  be  greatly  extended,  and  the  black  re- 
duced, varieties  might  occur  somewhat  resembling  some  varieties 
of  L.  crassipes,  but  would  be  at  oace  distinguished  by  the  diffe-

Oregon  and  Washington  Territory ;  one  pair.  The  antennae 
in  the  male  are  slender,  nearly  four-fifths  the  length  of  the 
body ;  scarcely  more  than  half  the  length  of  the  body  in  the  9 . 

This  and  L.  cubilalia  form  a  peculiar  group  in  the  genus,  hav- 
ing the  eyes  scarcely  emarginate  on  the  inner  margin,  and  the 
3d  joint  of  the  tanei  broader  and  more  deeply  bilobed  than  usual, 
agreeing  in  these  characters  with  Acmaeops ;  the  head  is  much 
less  constricted  behind  than  in  other  Lepturoe,  althuugh  it  is 
suddenly  narrowed,  and  the  angles  are  rectangular  and  rounded, 
almost  as  in  Encyclops  ;  the  front  is,  however,  not  vertital,  the 
transverse  impression  is  deep,  the  genee  rather  short,  the  epistoma 
and  mouth  moderately  long;  the  last  joint  of  the  palpi  is  but 
feebly  dilated,  and  squarely  truncate,  longer  tha  i  the  preceding, 
as  usual. 

I  would  associate  tliese  species  with  the  2d  division  of  Ac- 
maeops, but  the  antennae  seem  to  be  inserted  rather  behind  the 
line  joining  the  front  of  the  eyes,  as  in  other  Lepturu),  and  the 
general  appearance  is  more  suggestive  of  the  latter  genus.  They 
would,  however,  be  equally  well  placed  in  either.

Cape  San  Lucas ;  Mr.  Xantus.  This  species  seems  to  agree 
more  nearly  with  the  genas  to  which  I  have  referred  it  than  with 
liny  other  of  which  I  can  find  description.  I  should  refer  it  to 
Pogonocherus,  since  the  front  coxal  cavities  are  angulated  exter- 
nally nearly  as  much  as  in  that  genus,  but  tho  scape  of  the  an- 
tennae is  much  longer  and  more  slender,  as  in  Leptostylus,  and 
extends  to  the  lateral  spine  of  the  prothorax.  The  antennae  are 
about  one-fourth  longer  than  the  body,  and  clothed  on  all  sides 
with  long  hairs,  the  3d  and  4th  joints  are  nearly  equal,  the  5th 
and  following  diminish  rapidly  in  length.  The  prosteruum  is 
rather  narrow  between  the  coxae,  the  mesosternum  not  wide,  trun- 
cate and  subemarginate  behind,  the  middle  coxal  cavities  angu- 
lated externally,  though  not  open. 

The  body  is  clothed  with  dense  pale  brown  pubescence,  the 
antennae  are  annulated  and  punctured  with  darker,  the  disk  of 
the  prothorax  is  mottled  with  darker,  and  the  lateral  spines  are 
acute ;  the  base,  sides,  and  tip  of  elytra  are  dark,  with  still  darker 
spots,  leavinj^'  an  elongate  common  spot  of  pale  gray,  emarginate 
in  front  and  at  ihe  sides,  extending  from  the  humeri  for  two- 
thirds  the  length,  limited,for  one-half  its  length  by  a  well-defined 
carina,  extending  from  the  humerus,  and  becoming  obsolete  near 
the  tip,  which  is  rounded  ;  outside  of  this  carina  is  a  shorter  one, 
also  proceeding  from  the  humerus,  and  abbreviated  at  the  middle. 
The  body  beneath  is  clothed  with  pale-brown  pubescence,  and 
the  groove  and  tubercle  of  the  middle  tibite  are  feeble.  The  fly- 
ing hairs  are  very  long  and  numerous. 


LEPTOSTYLUS  Lbo. 
The  species  may  ha  arranged  as  follows  : — 

A.  Elytra  more  broadly  and  regularly  ronnded  at  tip ;  lateral  tubercles  of 
prothorax  not  prominent,  broadly  ronnded.  Palhrri  n.  sp.

Louisiana ;  this  species  is  suflBciently  distinct  by  the  disk  of 
the  elytra  being  flattened  in  front,  limited  each  side  by  an  oblique 
well-defined  line,  exterior  to  which  is  the  line  defining  the  abrupt

hind  tarsi  as  long  ps  the  two  following,  and  from  Liopus  by  the 
mesosternum  being  broad  and  truncate  between  the  coxae.  The 
thoracic  tubercle  varies  in  position  but  little,  and  is  about  one- 
fourth  to  one-third  from  the  base,  obtuse,  but  not  rounded  ;  the

asperities  (very  much  as  in  Leptostylus  aculi/er),  and  behind  the 
middle  several  of  these  combine  to  form  an  elevation,  which  runs 
transversely  from  the  side,  and  then  bends  abruptly  backwards, 
and  is  curved  to  the  suture.  But  the  most  striking  characters 
are  found  in  the  antennae;  which  are  4  or  5  times  as  long  as  the 
body,  very  slender,  fringed  with  short  fine  hair  beneath,  as  in  the

different.  I  can  find  nothing  of  importance  to  separate  it  from 
Pogonocherus.

DESCRIPTIONS   OV   NEW   SPECIES. 


The  pubescence  is  uniform  dirty  yellowish-brown,  and  rather 
coarse,  intermixed  with  short  suberect  gray  hairs  proceeding  from 
the  punctures.  The  usual  ridges  of  the  elytra  are  entirely  want- 
ing. The  front  coxal  cavities  are  angulated  as  in  the  other  spe- 
cies. The  body  beneath  is  finely  punctulate  and  pubescent, 
sparsely  punctured  with  fuscous. 

The  antennae  are  one-half  longer  in  % ,  and  but  little  longer 
than  the  body  in  9 .     The  largest  specimens  are  all  males.

Western  States  and  Texas.  Easily  distinguished  by  the  above 
characters ;  the  thoracic  vittae  do  not  extend  upon  the  head  ; 
the  elytra  are  coarsely  punctured,  and  rounded  at  tip  ;  the  inner 
division  of  the  claws  is  acute,  and  a  little  shorter  than  the  outer 
one,  though  more  nearly  equal  than  in  M.  femoralis.

Illinois ;  the  only  specimen  in  ray  collection  has  the  last  ven- 
tral segment  triangularly  excavated,  and  hairy  as  in  D.  ventralis, 
which  I  consider  as  the  9  of  D.  tenuipes  Hald.  It  differs  by  the 
nearly  smooth  thorax,  and  by  the  elytra  rather  longer,  narrowed 
and  more  dehiscent  behind  the  middle. 


*  Tlie  following  species  is  mentioned  by  Chevrolat,  Ann.  Ent.  Soo.  Fr., 
1862,  p.  256,  as  M.  pttsilla,  which  it  replaces  in  the  Antilles.

One  9 ,  San  Domingo,  Mr.  Gabb  ;  Cuba,  Dr.  Gundlaoh.  Very  similar  to 
M.  pnsllla,  but  the  sides  of  theprothorax  are  scarcely  dilated  at  the  middle, 
the  front  transverse  impression  is  wanting,  the  posterior  constriction  is 
less  deep,  there  are  no  dorsal  callosities,  and  the  elytra  are  comparatively 
shorter.  The  color  of  the  head  and  prothorax  is  light  and  dark  brown 
mixed ;  the  elytral  vittae  are  connected  transversely  near  the  base,  and 
about  the  rai<idlH,  but  frequently  disappear,  leaving  only  a  humeral  cloudy 
spot.  The  wings  as  in  all  the  species  of  the  tribe  are  very  iuiperfeotljr 
folded  at  tip.
